论文摘要

动词感觉歧义是NLP的一项众所周知的任务,目的是找到句子中动词的正确感。最近,通过利用模棱两可的动词的文本和视觉特征,导致新问题(Visual Verb Sense sisse disampain(vvsd)),在多模式方案中扩展了这个问题。在这里,考虑了与之配对的图像的内容,而不是动词出现的句子,可以分配动词的感觉。为此任务注释数据集比文本歧义更为复杂,因为将正确的感觉分配给一对$ <$ image,动词$> $需要非平凡的语言和视觉技能。在这项工作中,与文献不同,VVSD任务将在跨型半监督学习(SSL)设置中执行,其中仅需要少量的标记信息,从而极大地减少了对带注释数据的需求。歧义过程基于基于图的标签传播方法,该方法考虑了$ <$ image,动词$> $ $ $ $ $ $ $ $ $ $ $ $ $ $的单模式表示。实验是在最近发布的数据集经文上进行的,这是该任务的唯一可用数据集。所达到的结果的表现优于当前的最新边距,同时仅使用每种意义上的标记样品的一小部分。可用代码:https://github.com/gibg1an/tvvsd。

Verb Sense Disambiguation is a well-known task in NLP, the aim is to find the correct sense of a verb in a sentence. Recently, this problem has been extended in a multimodal scenario, by exploiting both textual and visual features of ambiguous verbs leading to a new problem, the Visual Verb Sense Disambiguation (VVSD). Here, the sense of a verb is assigned considering the content of an image paired with it rather than a sentence in which the verb appears. Annotating a dataset for this task is more complex than textual disambiguation, because assigning the correct sense to a pair of $<$image, verb$>$ requires both non-trivial linguistic and visual skills. In this work, differently from the literature, the VVSD task will be performed in a transductive semi-supervised learning (SSL) setting, in which only a small amount of labeled information is required, reducing tremendously the need for annotated data. The disambiguation process is based on a graph-based label propagation method which takes into account mono or multimodal representations for $<$image, verb$>$ pairs. Experiments have been carried out on the recently published dataset VerSe, the only available dataset for this task. The achieved results outperform the current state-of-the-art by a large margin while using only a small fraction of labeled samples per sense. Code available: https://github.com/GiBg1aN/TVVSD.
